Python 压缩图片

Question

from wand.image import Image 

image = Image(filename='screen.png')
width = image.width
height = image.height 

if (width > 1980):
    rate = width / 1980
    image.resize(1980, int(height / rate))
image.compression_quality = 80  #设置质量为 80%
image.compression='lzma'   # 采用 lzma 压缩算法
image.strip()   # 去掉图片中的注释
image.save(filename='bbbb.jpg')
